Can enclosing class access nested class?

I have the following code:

#include <iostream>
#include <string>

class enclose
{
    private:
        int x;
    public:
        enclose(void) { x = 10; };
        ~enclose(void) { };

        class nested1
        {
            public:
                void printnumber(enclose p);
        };
};

void    enclose::nested1::printnumber(enclose p)
{
    std::cout << "the number is " << p.x << std::endl;
}

int main()
{
    enclose example;

    example.printnumber();
}

I am aware that the last line example.printnumber(); is incorrect. However, I would like to know if there is any way that the enclosing class can access the nested class' functions. How can example access the printnumber() function?

Can enclosing class access nested class?

Yes, if the enclosing class have an instance (an object) of the nested class.

A class is a class is a class... Nesting doesn't matter, you must always have an instance of the class to be able to call a (non-static) member function.
